We tried:

 

nifi.web.https.host=localhost

 

nifi.web.https.host=

 

nifi.web.https.host=0.0.0.0

 

no impact, UI still would not bind to HTTPS port.

 

We decided to leave it at 0.0.0.0 as that’s the recommended configuration in 
the Administrators guide for binding to all interfaces.

 

Thanks,

Subject: Re: NiFi UI Not Starting

 

Dan,

 

I am wondering if it is an issue with binding to 0.0.0.0 — are there any 
differences between the test and production server non-NiFi configurations that 
would prevent this? Can you try setting nifi.web.https.host=localhost instead?

Hi Joe, 

I’ve attached relevant files… tried to redact sensitive info… hope I didn’t cut 
too much from the logs…

Thanks,
Dan

   Dan - are you able to share the nifi-app and nifi-bootstrap logs?

   Thanks

Hello,



I’m having an issue getting NiFi to start correctly. Here’s my situation:

I’m currently running v0.7.0.
I have a production server and a test server, with identical configurations
(OS, Java, Java security config, nifi versions, nifi configs,
keystores/truststores, etc).
When I run nifi via normal HTTP (e.g. no security) in both Prod/Test they
both start & load the UI as expected.
When I run nifi via HTTPs (e.g. security settings) the Test server starts
and loads UI as expected.
However, on the Prod system, I receive the following error and java does not
bind to 8443:



2017-07-25 16:30:51,346 WARN [main] org.apache.nifi.web.server.JettyServer
NiFi has started, but the UI is not available on any hosts. Please verify
the host properties.



I reviewed the source code and it looks like this error is logged when the
“URLs” is empty.
Here is what I *think* are the relevant properties from my nifi config, when
trying to start up using TLS (running on both Prod & Test), again, Test
starts fine, Prod throws the error above.



# Enable TLS

nifi.web.http.host=

nifi.web.https.host=0.0.0.0

nifi.web.http.port=

nifi.web.https.port=8443

nifi.security.keystore=<path_to_keystore>

nifi.security.keystoreType=JKS

nifi.security.keystorePasswd=<keystore_password>

nifi.security.keyPasswd=<key_password>

nifi.security.truststore=<path_to_trust_store>

nifi.security.truststoreType=JKS

nifi.security.truststorePasswd=<trust_store_password>

nifi.security.needClientAuth=true



Again, I’ve manually validated the correct paths, correct passwords to JKS
files., etc.
I’ve verified that there are no other processes binding to 8443 possibly
blocking nifi from the port.
I’ve tried changing the port number (e.g. to 8445), no effect
I’ve turned off IPTables.
Generally, I run nifi as a “nifi” user, however, I’ve also tried running it
as root to see if that had an effect of allowing the UI on Prod to start…no
impact.
I’ve tried also starting up nifi with a blank/default flow file, no effect.



Any thoughts/suggestions on what I can do next, short of uninstalling nifi
and reinstalling?



Thanks,

Dan
